I keep these warning cones in my shop. They are very bright colors so as to serve as a warning and precaution, which saves me a lot of unnecessary trouble. The base of these safety cones is fillable, and I filled them with about 8 pounds of water to make them more stable, to adjust the shape of the safety barrier as needed, and to move and store them easily. It's a perfect product.Very cute easy to put tiger but should include sandFirst, they arrive quickly. Simple setup and it works immediately. Good corrosion resistant materials and perfect color, to meet our needs.I thought they would be taller. Pretty flimsy construction too.It doesn't hold up and the support disc leakThere is a cement pit in the driveway of the house, so there is no time to repair the driveway. Buy 4 pack delineator post cone to protect it first, so as to prevent parking into the pit after work at night. The color is bright and the base of the delineator post cone is stabilized with water to prevent it from being blown down by the wind. The effect is very good.There is no retention of the posts to the bases. The posts easily fall off the base, making a very inefficient or effective barrier. Even the weight of the chain on the end post pulls the post off the base.They really do not do what they are supposed to do. The two piece design with no retention is terrible. Maybe add threads to the base of the poles so they can screw into the bases?Love that these can be broken back down. Good quality. The day we used them we didn’t fill the bottom with water and they still stayed put.
